Subversive politics: Subversion refers to an attempt to overthrow structures of authority, including the state. It is an overturning or uprooting. The word is present in all languages of Latin origin, originally applying to such diverse events as the military defeat of a city.

Subversive activity: Subversive activity is the lending of aid, comfort, and moral support to individuals, groups, or organizations that advocate the overthrow of incumbent governments by force and violence. All willful acts that are intended to be detrimental to the best interests of the government and that do not fall into the categories of treason, sedition, sabotage, or espionage are placed in the category of subversive activity.

And last but not least:
Subversive behavior: Subversive behavior is to undermine somebody with various trick (lies, cheats, backstabbing, false advice etc...) where the intent or goal is not visible at all.

The subversive person often assumes little responsibility and occupies a border position in the project. To the group says how bad is the management to the management says how bad is the group and to the big boss says how bad are both and how good is he and he should be made boss.
He's goal is to undermine the project so that it fails and he can emerge as the new knows it all leader.

Subversive is a newly coined term for emergeing youth that express themslves artistically through blending whats Socially Taboo/Underground and what is Mainstrem.

They also break free of any label they recive by what is oppisite to that particular label;

ie: If they like Death Metal they will listen to EuroPop and wear bright colours

Often mistaken for being Goths, Emos or whatever else is currently trendy. Subversives seek out the most extreme in cinema and music.

They dress in whatever they want. But some of the girls like to dress in perky-goth/pink attire. They are often labeled as Angsty, Psycho or Homicidal. However they are very well aware of the difference between shock-vaule art and real life.
